But this theory is dismissed on two grounds: cellphones didn’t exist in the 1960s, and the frequency emitted by both cell towers and the electric grid can be easily blocked by metal enclosures. Many have pointed to the electric grid or cellphone towers. He then examined the competing hypotheses for the source of the Hum. It first appeared in the United States in the late 1980s, in Taos, New Mexico. It was written in 2004 by geoscientist David Deming (who’s also a Hum hearer).ĭeming began by describing the standard history: The Hum was first documented in the late 1960s, around Bristol, England. I eventually came across one of the few serious papers on the topic. For others, the Hum is loud, relentless and life-altering. It can start and stop suddenly or wax and wane over time. For some, it’s a distant rumbling or droning noise.

The classic description of the Hum is that it sounds like a truck engine idling. The questions motivating me and thousands of others were the same: “What’s causing this? Can it be stopped?” One geoscientist’s theory I was part of the small fraction of people who can hear what is called the “Worldwide Hum” or, simply, the “Hum.” When I searched on the internet for “unusual low-frequency humming noise,” I soon realized that others had conducted the same search. I was able to rule out obvious sources: industrial activity, marine traffic, electric substations and highway noise. I drove for miles in every direction, and it was still there in the background when I stopped the car. While I couldn’t hear the sound outdoors, I could still hear it in my car at night with the windows closed and the ignition off.
